LH_PACKAGES and LH_HOOKS

I have a few debian packages inside of "/config/chroot_local-packages/".
Let's say they are mickeymouse.deb and donaldduck.deb.
And let's say inside of "/config/chroot_local-hooks" I have
01-update_password.sh.
The wiki says this:
"To add a specific debian package, just move the .deb into
config/chroot_local-packages/ directory. Packages included in
this directory will be copied in the chroot and installed
automatically."
Is that the current truth?
The manual gives me a different impression:
5.1.3.1. The LH_PACKAGES variable
To install additional packages, simply add them to the
LH_PACKAGES variable in config/chroot. For example:
LH_PACKAGES="package1 package2 package3 ...
So, inside of the /config/chroot file am I suppose to specify the .deb packages?
Example:
# $LH_PACKAGES: set packages to install
# (Default: empty)
LH_PACKAGES="mickeymouse.deb donaldduck.deb"
Furthermore, I want to change the root password, so I want to know if I
have to specify the file(s) I want executed.
Am I suppose to specify the scripts I wanted executed?
Example:
# $LH_HOOKS: set hook commands
# (Default: empty)
LH_HOOKS="01-update_password.sh"
